Mars does so have an atmosphere but it is much thinner than that of Earth. I
believe the major problem with the evolution of life on Mars was that the
output of carbon dioxide by the martian volcanos dropped away too soon.
Mars then cooled to a point where water could no longer exist in liquid form
and hence life became impossible. Life did not exist long enough for
intelligent life to evolve on Mars.
